Nextflow v 21.04.3 doesn't support ignite

[pbardou]

Hello,

We need to use nextflow with charliecloud and -with-mpi (ignite).
When we tried nexflow 20.10, ignite is ok but not charliecloud.
When we tried nextflow 21.04, charliecloud is ok but not ignite.

Is there Nextflow version supporting both?

Thanks for your help
Regards

I believe that ignite support has been factored out of the main codebase into a plugin starting with the 21.04.0 release
So you'd have to add this block to your nextflow.config, in order to use it:

plugins {
  id 'nf-ignite'
}

I try but without success...

Channel.fromPath('reads/*_1.fq.gz').set{ samples_ch }

  """
}
